Filter by:The purpose of this research study is to observe the patient's clinical care and how EYLEA® HD is used as a treatment in real-world settings. Patients are asked to join the study because they have either neovascular age-related macular degeneration (nAMD/wet age-related macular degeneration [AMD]) or diabetic macular edema (DME). Patients cannot have used EYLEA® HD in the past and the doctor must be planning to treat nAMD or DME with a new prescription of EYLEA® HD (aflibercept 8 mg).
Biodiversity is essential for nature and human well-being. Land use has reduced biodiversity in cities, which weakens the functionality of the urban ecosystems and the well-being of citizens. This may also increase the risk of immune-mediated disorders among urban dwellers. In Biodiversity interventions for assisted living centers (BIWE 2), microbial biodiversity interventions are performed to increase biodiversity in urban housing units for people with autism spectrum disorder, disabled people and elderly. Results from the intervention trials are combined with publicly available land cover and ecological data. These are analyzed from the viewpoint of shifts in ecosystems and human well-being and immune regulation, ecological quality, and urban planning. The investigators set up an intervention study in which yards of the housing units are rewilded with diverse vegetation and decaying deadwood and plant residuals. The investigators aim to evaluate the effect of rewilding, and yard management practices on commensal microbiome, cortisol levels and well-being and salivary cytokine levels, and gene pathways.
My Space aims to identify the ontogenesis of spatial representation through cross-sectional and longitudinal studies in infants, children, and adolescents with typical and atypical development (visual impairments). The results will serve for the design and development of a novel multisensory device for sensorimotor rehabilitation in blind children from the early stages of life.
The broad goal of this clinical trial is to demonstrate whether a one-month rehabilitative training with our medical device, iReach, can promote the recovery of spatial and sensorimotor abilities and the cortical reorganization process in children with visual impairment between 3 and 36 months of age.
Purpose of this study was to assess the relationship between the visual impairment degree and the level of children's fundamental motor skills, balance and bilateral coordination.
Purpose: This project aimed to examine the effects of laughter yoga, which is accepted as an international nursing initiative, on loneliness, anger and salivary cortisol levels in visually impaired individuals. When the national and international literature was examined, no project was found that measured the results of laughter yoga as an intervention for visually impaired individuals. For this reason, planning an original project in this field aims to contribute to the literature. Thanks to the evidence obtained, laughter yoga, an innovative approach, can be disseminated in institutions and organizations serving visually impaired individuals as an evidence-based practice that can improve the social skills of individuals. Scope and Target Audience: The project will be carried out with visually impaired individuals receiving services in the Disabled Persons Department within the Atatürk Provincial Public Library located in Konak district of Izmir. In this section, services are provided to 250 members who actively use the library and to visually impaired people from all over Turkey. Method and Expected Result: The project was planned in a randomized controlled, pre-test post-test, single-blind follow-up consultancy design. With this initiative, a social rehabilitation environment will be provided for visually impaired individuals by taking an approach based on respect, understanding and awareness. Laughter yoga is expected to reduce the level of anger and loneliness in visually impaired individuals. At the same time, laughter yoga is expected to reduce cortisol levels, which are known to increase when faced with stress factors, and increase serotonin, which is associated with happiness and vitality, and endorphine, known as the body's natural painkiller. With laughter yoga sessions, a social environment will be created where visually impaired individuals will have an active and independent experience. Thanks to the expected evidence, laughter yoga can be popularized both in visually impaired individuals and in individuals with other disabilities. Within the scope of protecting and improving health, laughter yoga can be planned to be carried out as a routine nursing practice in disabled centers. Thus, by creating an environment where visually impaired individuals and nurses come together, a more accessible health service will be provided to individuals with special needs.
In patients with hemianopsia following stroke or brain injury, we will determine if stimulating the visual field with images from a PowerPoint slide set can increase the visual field.
Clinical vision measurements usually involve printed charts with an eye care professional interpreting patient responses to generate a score. Those scores determine the need for or outcome of treatment. Detecting change can be improved with strict procedures/scoring, lending itself to computerisation. This in turn allows integration with electronic medical records. Many eye tests could be computerised in this way. At Guys and St Thomas' NHS Foundation Trust, the investigators have developed and validated a computerised test of distance visual acuity, called COMPlog which is now in widespread use. The investigators now want to increase the range of tests available. There is also a need to longitudinally monitor for adverse change. Such monitoring must be developed to keep false positive and false negative change detection to a minimum. The aims of this two year linked program are to: Part A) validate an extended range of computerised vision measurement tests against their gold standard hard copy printed equivalents. Some of these tests are designed for use in children and all are meant to quantify both normal and impaired vision. Patients of all ages and visual function will therefore be recruited from St Thomas' Hospital. The specific tests we aim to validate are logMAR Letter Near Acuity, Word Near Acuity, Letter Contrast Sensitivity, Auckland Optotypes Picture Acuity, Low Contrast Letter Acuity, Stereoacuity and Vanishing Optotypes. Patients will undergo test-retest measurements with up to two of these. Part B) Iteratively develop an application for use in home monitoring of subjects at risk of treatable vision loss due to age related macular degeneration. All computerised tests in parts A and B will be performed on prototype software. Eye patients will be recruited as subjects. Patients recruited to part A will undergo tests on one day for up to an hour, subjects in part B will participate for between 1 hour and two months.
Visual impairment is use to describe any kind of vision loss, whether it's someone who cannot see at all or someone who has partial vision loss. visual impairment is classified on the bases of visual acuity like mild, moderate, severe, profound, near total visual impairment, no light perception (NLP). Multisensory integration refers to a broad class of computations involving multiple sensory modalities in which information is integrated to produce an enhanced (or degraded) response.A Randomized control trail will be conducted at rising sun institute for disable children. Total sample size will be of 40 participants. After meeting the inclusion and exclusion criteria participants will be divided into two groups .Group A Control group will receive conventional therapy program. Place toys/objects inside and encourage the student to reach in and pull them out as well as put them back in. Give the student objects that can be put together and pulled apart. Group B will be treated with standard activity based therapy In which place different( nuts, screws, bullets, coins, paper clips, coloring ,scissor cutting with different shapes, Simulated feeding (by collecting beans with a spoon and transferring them into a container),transfer light and heavy weight objects into empty box. Nine whole peg tests are used to measure fine dexterity in visual impaired children. Jebsen Taylor hand function test for quantify motor hand function test. Total time for treatment per session will 45 minutes and duration of treatment will be 12 weeks, four days a week.box and block test used to improve manual hand dexterity. Assessment will be taken pre treatment, mid treatment at 4th week and 8th week and post treatment after 12th week. Data will be analyzed by SPSS
Development of the visual system immediately starts after birth via visual stimuli and interactions with the environment. The World Health Organization (WHO) has categorized visual impairments with respect to the best-corrected visual acuity as follows: blindness (Snellen visual acuity of 3/30), severe visual impairment (Snellen visual acuity between 6/60 and 3/30), moderate visual impairment (Snellen visual acuity between 6/18 and 6/60), and mild or no visual impairment (Snellen visual acuity of 6/18). The proper function of hands, particularly in delicate activities, depends on the interaction between the various regions of the brain, particularly, the sensory and motor cortex. Sensory stimulation can be used in such children to improve their manual dexterity and therapeutic interventions can be applied to gain hand strength. Developing skillful hands is a necessity in blind children as it often compensates for their missing vision. This study will focus on effectiveness of hand grip strength and manual ability with sensory stimulation in children with moderate to severe visual impairment. Theraputty hand exercises and sensory stimulation techniques will be used.
